System justification (SJ) is an important construct in social psychology that has received considerable attention over the past three decades. At the empirical level, system justification is examined by means of a specially developed System Justification Scale (SJS), which is designed to explain how individuals accept justice, whether they consider a given social order to be fair, how they evaluate the conditions in the country in which they live, how they accept social change, or to what extent they express compliance with established rules. System justification involves not only those who benefit from the existing social order, but also those who are disadvantaged. In their case, system justification mitigates negative perceptions of objective inequalities and asymmetries. Empirical evidence suggests that system justification may also be associated with higher perceived quality of life. The present study translated and validated the SJS, providing complex and detailed information on the psychometric properties of the scale. In addition, the scale's internal consistency, unidimensionality, and construct validity were examined. The conclusions presented are based on the results of exploratory factor analysis, internal consistency assessment, analysis of variance, correlation analysis, and confirmatory factor analysis. Results were obtained from face-to-face survey data collected from a sample of 1419 individuals representing the Czech population aged 18-79 years. Since the SJS showed high internal consistency, adequately discriminated levels of system justification, and had robust psychometric properties, it could be recommended for further use.
系统正当性（SJ）是社会心理学中的一个重要概念，在过去三十年中受到了相当多的关注。在实证层面，通过专门开发的系统正当性量表（SJS）来检验系统正当性，该量表旨在解释个体如何接受正义、他们是否认为特定的社会秩序是公平的、他们如何评价自己所生活国家的状况、他们如何接受社会变革，或者他们在多大程度上表示遵守既定规则。系统正当性不仅涉及那些从现有社会秩序中受益的人，也涉及那些处于不利地位的人。就后者而言，系统正当性减轻了对客观不平等和不对称的负面认知。实证证据表明，系统正当性也可能与更高的生活质量感知相关。本研究对SJS进行了翻译和验证，提供了有关该量表心理测量特性的复杂而详细的信息。此外，还检验了该量表的内部一致性、单维度性和结构效度。所呈现的结论基于探索性因素分析、内部一致性评估、方差分析、相关分析和验证性因素分析的结果。结果来自对1419名代表18 - 79岁捷克人口的个体进行面对面调查收集的数据。由于SJS显示出高内部一致性、能充分区分系统正当性水平且具有稳健的心理测量特性，因此可推荐进一步使用。
